DON'T BUY THIS DEVICE ! It's bulky but has tiny battery, it's USB 2.0 rated but transfer speed is roughly 4 MB/s, it's supposed to copy flash cards, but transfer speed is VERY lousy. You can use it as card reader which require external power - that's where this device performs as good as $5 alternative.Once again, DON'T BUY THIS !
